Sean Mathias, who directs the incoming Rialto staging of “Breakfast at Tiffany’s,” will helm. Stuart Thompson, the producer behind the current revival of “Cat on a Hot Tin Roof” starring Scarlett Johansson, and Nomango Prods. produce.

McKellen hasn’t appeared on the Main Stem since the 2001 revival of “Dance of Death” (also directed by Mathias), while Stewart’s most recent outing on the Rialto was the short-lived 2010 production of “A Life in the Theater.”

McKellen and Stewart co-starred in a Mathias-helmed “Godot” on the West End in 2009. The new production of “No Man’s Land,” meanwhile, will bow in an out-of-town tryout this summer, with location and timeline still to be set.

Both “Godot” and “No Man’s Land” are four-character plays. Additional actors for the shows are not yet cast.

The 1953 play “Godot” centers on two tramps who kill time together while they wait for the mysterious title character. Pinter’s 1975 outing “No Man’s Land,” meanwhile, follows a pair of writers whose prior relationship is revealed to be increasingly enigmatic over the course of a drunken evening.

Creative team for both shows, which will play in rep, include Stephen Brimson Lewis (sets and costumes) and Peter Kaczorowski (lights). Further details, including dates and theater for the fall run, have yet to locked.
